| 摘 要： | 鞘氨醇单胞菌QYY菌能以溴氨酸为唯一碳源、氮源和能源生长。考察了用海藻酸钙包埋该菌细胞对溴氨酸废水进行处理的降解和动力学过程。确定了固定化鞘氨醇单胞菌QY(Y以下简称固定化菌)处理溴氨酸废水的最适条件为:接种量10mL固定化菌,摇床转速100r/min,pH7,温度30℃。最佳降解条件下,固定化菌降解溴氨酸的过程符合Haldane模型。

| Abstract: | Bromamine acid (BAA) can be used by Sphingomonas xenophaga QYY as sole carbon, nitrogen and energy source. Calcium alginate entrapment method was selected to immobilize the cells. Characteristics and kinetics of biodegradation process for immobilization cells were investigated, with the optimal conditions of inoculation 10mL of immobilization cells; pH 7, temperature 30℃ and shaking speed 100r/min. Under the optimal conditions, the biodegradation of BAA can be described as Haldane model. |
